Food Web and Food Chain
Food Web and food webs are representations of the predator-prey relationships between species within an ecosystem or habitat
Food Chain
They are called producers because only they can manufacture food from inorganic raw materials.
This food feeds herbivores, called primary consumers.
Carnivores that feed on herbivores are called secondary consumers.
Carnivores that feed on other carnivores are tertiary (or higher) consumers
